Talent show sensation Susan Boyle has been voted through to the semi-finals of "Britain's Got Talent," the show that rocketed her to global fame last month.

Boyle is now the runaway favorite to win the final which takes place Saturday, May 30, in England.

Boyle jumped for joy and said: “I am on top of the world. It’s fantastic!” when Simon Cowell said judges had voted her through to the next stage.

Boyle, 47, became an overnight success with her audition on "Britain's Got Talent."

Since then, her rendition of "I Dreamed A Dream" has been viewed more than 58 million times on YouTube, with a combined 100 million views overall.

Hollywood star Demi Moore is one of those fans. In her Twitter feed, Moore has said that Boyle's voice "made her teary."

Boyle, who lives alone with her cat Pebbles, is the youngest of nine children. Their parents, Patrick and Bridget were both Irish immigrants who moved to Scotland in search of work.

Brother Gerry said; "She had a tremendous reaction because of the phenomenon that is YouTube — it's now all over the world and she's coping rather well, but I think some of the reality is now starting to sink in."

As an adult, Boyle paid several visits to the Catholic shrine of Knock in Co Mayo where she would sing.

She said the death of her Irish immigrant mother Bridget had inspired her to enter the TV talent show. "I wanted to show her I could do something with my life," Boyle said.

Neither Boyle nor the show would reveal what song she will sing for the semi-final.
